Abstract
A steam line is connected to the oil lines supplying feed to a carbon black reactor and valves are provided in each of the steam and oil lines so that either or both steam and oil can be fed to the oil tube emitting feed into the reactor. To change an oil nozzle without interrupting production, oil flow to a single nozzle is cut off and steam flow is provided while the nozzle is removed from the reactor. Steam flow is again provided as the replacement nozzle is inserted into the reactor and when it is in place, steam is cut off and oil flow resumed.
